13 Migration helpers scripts/rename.pl and include/mbedlts/compat-1.3.h are
14 provided.
15 * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
Manuel Pégourié-Gonnard6963ff02015-04-28 18:02:54 +020016 * The following _init() functions that could return errors have
17 been split into an _init() that returns void and another function:
18 mbedtls_ccm_init() -> mbedtls_ccm_setkey()
Manuel Pégourié-Gonnard8f5fd312015-04-24 14:42:34 +020019 * In the threading layer, mbedtls_mutex_init() and mbedtls_mutex_free() now

Manuel Pégourié-Gonnard348bcb32015-03-31 14:01:33 +020071 * Support for RSA_ALT contexts in the PK layer is now optional. Since is is
72 enabled in the default configuration, this is only noticeable if using a
73 custom config.h
Manuel Pégourié-Gonnard606df8c2015-03-27 17:13:17 +010074
Manuel Pégourié-Gonnardd54e6172015-04-28 17:56:12 +020075Reauirement changes

Manuel Pégourié-Gonnarde6efa6f2015-04-20 11:01:48 +010083 extendedKeyUsage on the leaf certificate was lost (results not accessible
